Astronauts John M. Grunsfeld red stripes on suit, payload commander, and Richard M. Rick Linnehan, mission specialist, participate in the first of five STS-109 Extravehicular Activities EVAs to perform work on the Hubble Space Telescope HST. Linnehan and Grunsfeld are preparing to stow an old solar array in the Columbia's payload bay that will be replaced by a new one.
